Which handheld system was Mario Kart DS made for? Mario Kart DS was made for the Nintendo DS handheld system.

Nintendo released Mario Kart DS in 2005 as the fifth main game in the Mario Kart series. It was designed for Nintendo's dual-screen handheld, using the upper screen for the race and the lower touchscreen for maps, status information, and other interface features.

The game expanded the series with 32 courses: 16 new tracks and 16 retro tracks returning from earlier Mario Kart games. It also introduced Mission Mode and was the first Mario Kart title to support online play through Nintendo Wi-Fi Connection, allowing players to race over the internet.

The Nintendo DS is easy to confuse with the later Nintendo 3DS, but Mario Kart DS was released for the original DS family. It was not a PlayStation Portable or Game Boy Advance game. With about 23.6 million copies sold worldwide, it became one of the best-selling games for the Nintendo DS.
